Burstyn joins ‘Political’ cast

Thesp set for USA Network show

Ellen Burstyn is the latest thesp to join the cast of USA Network’s “Political Animals.”

She will play the mother of Sigourney Weaver, a divorced former first lady and newly appointed secretary of state who throws herself into her job when her marriage falls apart and a presidential bid comes up short.

Set to air this summer, the six-episode project from Greg Berlanti and Warner Horizon Television may become a full-fledged series. Production is set to begin later this month.
